I think he is referring to the Tanner quest, as that's the only basement with the Rune Assassins (nasty) and Ghasts. Stoneskin doesn't protect you from the Ghasts hold technique, and nither does mirror image IIRC. The Rune assassins are particually nasty as they are level 12 fighters/level 12 thieves I think. Use skull traps and fireballs to kill the ghasts quickly, and run upstairs and save before the Rune's reach you. Stoneskin will help you here, as will mirror image and protection from magical weapons (which you may not have yet). Cast horror to scare them, then bombard them with magic missiles, fireballs, cone of cold and all other offensive spells. The area effect ones will be absorbed by mirror image so your mage will be unharmed.
To gain XP, try the harpers quest after rescuing Renfold (occurs randomly walking from location to location). They give you 20,000 XP just for picking up a bird!!!
Do the Sir Sales quest and Dawn Ring quest at the temples for little or no fighting and decent XP for you solo char.
Circus quest has minimal fighting since most are illusions.
Give littleman the bear back to the boy in the graveyard and find a caretaker for the orphan. That's just a few off the top of my head, I'm sure there are loads more.
